7. fresh air

To storey high Villa or Office, and other commercial housing, conditions should be used in outdoor air conditioning tank or plate-fin heat exchangers full to fresh air. Use fresh air conditioning tank, air supply general processing to indoor enthalpy of the status parameter. To reduce indoor air blower plate Tube, fresh air the best treatment to indoor status points, wet bars and 90% relative humidity line intersect. In addition, the design also must pay attention to the ventilation effectiveness: supply sufficient fresh air, appropriate exhaust volume, ideal to exhaust layout and airflow organization helps improve ventilation efficiency, improve the indoor air environment. SARS outbreak makes people aware of the air-conditioning system should have the ability to deal with biological and chemical pollution. First, the new style-port location selection to fit, you must ensure that the new style air cleaner environment around the mouth, the inhalation of air is fresh and clean outdoor air, strictly prevent airflow ventilation system; in addition, short circuit in the new style air outlet is generally only set at the filter, this is set to normal atmospheric dust filtration efficiency is not high, pollutant particle size may be larger than dust particle size smaller, lower filtration efficiency may, therefore, in order to effectively filter dust and bacteria, it should be in the new style air-port is set to one early and one effect filter combinations, this filter combination of filter dust effect is clear, and filtration efficiency 99.9%; second, from the dusty pollution, mainly dealing with filter regular cleaning, disinfection, or replace, reduce the filter and the dust in the wind pipe, for air conditioning system cooler, condensate water disk and humidifiers to regular cleaning and disinfection.

8. vibration and noise reduction

Refrigeration and air conditioning equipment for vibration and noise is undoubtedly an important impact on the user, and in domestic refrigeration equipment special prominence in the Act. In domestic central air conditioning unit, the most important source of the noise from compressors and fans, so the two parts of noise control is very important. Unit as a whole must be considered when designing adequate vibration and noise reduction measures. On indoor noise standards are not met requirements of the indoor unit in design installation should take appropriate measures.

9. Unit corrosion

Since air conditioning is installed in host General roof or balcony, possibility for perennial from Sun and rain. Especially in some urban air pollution and acid rain, salt in the air of coastal areas, some units with 1 ~ 2 years already rusty, severely reducing the life of the unit. Therefore, manufacturers in product design and user equipment selection should be attracted enough attention.

Conclusion: in short, air source for household central air conditioning system is similar to household appliances, to millions of households, must have a high degree of reliability, easy operation and low failure rate, guarantee to provide users with a safe, healthy, efficient, pleasant and harmonious living environment.
